Electrically tunable detector for millimeter frequency band

Abstract

An electrically tunable detector for sub-THz-frequency radiation based on Si CMOS technology is proposed. The tunability range of the implemented detector covers frequencies from 150 GHz up to 270 GHz with optical responsivity close to 1 kV/W and noise equivalent power below 20 ${\text{pW}}/\sqrt {{\text{Hz}}} $. Potential applications include microwave bio and medical sensing, spectroscopy, amateur radio use and nondestructive imaging.
